What's up

Energy is not a separate layer of industrial transformation. It runs through almost every technical decision, how electrical power is converted and controlled, how much energy is spent cooling critical equipment, when industrial assets should operate, and what can still be recovered from the emissions a process generates.

This is why Energy & Power is a transversal theme at A6K, present in our collaborative research projects, our industrial demonstrators, our infrastructure choices, and across the companies that work here, from start-ups to industrial groups and research centers. Together, they show where industrial energy is won or lost.

From the converter to the chimney

It starts where electricity is converted. In rail, multiple power schemes are not a design choice but a constraint. A train crossing Europe meets different voltages and electrification systems from one country to the next, and each configuration has tended to require its own dedicated control electronics. The M&SSCoT project, funded by the Walloon Region, brings together Alstom Belgium, Thales Alenia Space Belgium, CETIC, Deltatec and Alpha Innovations around a single control architecture, built on one elementary structure and adaptable to any power scheme, now heading toward an industrial demonstrator, a railway power converter tested in real operating conditions.

Another challenge to tackle is heat transfer, and conventional cooling can consume a large share of electricity power. Calyos works on fully passive two-phase cooling, using the vaporization of a dielectric fluid in a closed loop, without pumps and without water, up to 50% less cooling energy, no maintenance, and silent operation under vibration, dust or extreme temperatures. In 2026, it was selected for NATO's DIANA program, out of more than 3,600 proposals, under the Energy & Power challenge.

Then comes the question of when, and where. On average, only around 37% of the renewable electricity produced by large companies is consumed on site, while hourly prices swing widely and can even turn negative on sunny or windy days. Wise.Energy works on that disconnect. Its Wise.Brain system combines weather forecasts, expected on-site generation, market prices and equipment flexibility to shift loads toward the best hours automatically, with a first industrial deployment at Deltrian showing savings of up to 80% on the flexible portion of the bill.

Insens reads the voltage and current signals feeding industrial motors, from a single sensor placed in the electrical cabinet, and reports more than 15% less electricity consumed and 7% more line availability on sites such as TotalEnergies and Aperam. Fuzz supervises distributed assets, charging stations, heat pumps, batteries, and adjusts them to variable prices. And Mitis develops oil-free micro gas turbines based on flameless combustion, producing heat and electricity at the point of use, from a wide range of fuels including biogas, with very low emissions and no lubricated bearings to maintain.

What remains is the carbon that efficiency alone cannot remove. Some CO₂ is linked to the chemistry of production itself. More than half of global anthropogenic emissions come from flue gases with concentrations between 4 and 15%, a range for which no commercially viable capture technology exists today. ARK Capture Solutions targets that gap with CO₂ DISRUPT, a €5.6 million pilot project run with industry players, a mobile unit designed to capture one to two metric tons of CO₂ per day at the chimney outlet, to be tested in three different industrial environments.

Our community, not a catalog

None of this fits into neat categories, and that is the point. Energy is not only the business of companies that sell energy solutions. Here it often appears as a property of technologies built for something else entirely.

Vertical Compute stacks memory directly on top of logic to break the memory bottleneck of AI computing, cutting data movement from centimeters to nanometers and targeting up to 80% energy savings on the same workload. I-care's wireless vibration sensors run more than five years on a single battery, so that monitoring a machine continuously adds almost nothing to a plant's energy demand. The same requirement shapes our own infrastructure with Lucia, the Walloon Tier-1 supercomputer operated by Cenaero and hosted at A6K, ranked 89th in the November 2025 Green500, and the future A6K & E6K campus applies it to the buildings themselves, with a gas-free site, 1,000 photovoltaic panels, heat recovered from data center and supercomputer activity, and what is set to become Belgium's largest aquathermal installation.

And the community keeps growing. Exergia, specialized in the transformation of industrial thermal processes, Jetpack.ai, which brings data and AI to energy forecasting and simulation, and 3J Consults, which advises industrial sites on energy optimization, are among the companies that recently joined the conversation.

The Cleantech Spotlights, held with District Cleantech in February 2026, brought thirteen more face to face with industrial players, researchers and investors. Because an industrial energy solution has to confront questions that rarely appear in a pitch deck. Can it integrate with existing equipment? Can production be shifted without missing delivery targets?

No single technology solves the industrial energy challenge. Each problem calls for different capabilities, different actors and different forms of evidence. Our role is not to place them under one broad label, but to connect technical capabilities with industrial needs, and to build a path from an idea to a solution that can be challenged, tested and measured. That is where Energy and Power becomes tangible, not in a catalog of technologies, but at the points where energy is converted, consumed, produced or lost.

Bring us the point where your energy is lost

A motor that draws more than it should. A process that cannot shift when prices turn negative. Heat that leaves your site. Emissions you cannot yet avoid. Tell us where it happens, and we will turn it into impact with the right technology, the right partners, and a method to measure whether it works.
